This is a set of cute five-petal flower-shaped cutting dies. 【Flower Sizes】Approx. 15mm, 25mm, 35mm Ideally, a press machine is best, but you can also cut by tapping if you don't have one. It's better to use a rubber mallet when tapping. Place the leather on top of the cutting die and tap with a rubber mallet or wooden mallet. The blade is sharp, so please be careful not to touch it.
